Why the class interval is start with 20-31? Can u show me how to compute that? ( This is a follow up question)

Using the data below make a frequency distribution table containing the following: 1. classes with the lower and upper limits 2. class boundaries 3. tally 4. frequencies 5. class marks 6. cumulative frequency Data: Below are the number of patients in each day of the month of November 2019. 37 26 76 65 83 78 59 85 84 43 77 66 62 58 60 63 72 86 78 75 45 73 63 78 54 70 53 62 74 91 Expert Solution Step 1: Introduction Frequency distribution table : A distribution table is one approach to organize knowledge to form it a lot of intelligible. to make a distribution table of this kind, initial write the category intervals in one column. Then, add up the numbers in every class supported what number times it seems. Finally, within the final column, enter the frequency. A classified distribution table is that the distribution table represented on top of. Step 2: Solution FREQUENCY DISTRIBUTION TABLE : class Class Frequenc Class boundari Tally C.F interval mark es 19.5 - 20 - 31 1 25.5 1 31.5 31.5 - 32 - 43 37.5 3 43.5 43.5 - 44 - 55 II 3 49.5 55.5 56 - 67 55.5 - 67.
